Answer:
3. An oxygen atom with 8 electrons, 8 protons, and 9 neutrons .
Explanation:
if an atom contains equal numbers of protons and electrons, the atom is described as being neutral.
Answer:
Explanation:
Beta decay conserves the lepton number. In 
decay, the atomic number of the element increases which is accompanied by the release of an electron antineutrino, 
.
For example:-
The decay of silicon-32 is shown below as:-
Answer:
Pb(NO3)2 + 2NaCl = 2NaNO3 + PbCl2
Answer:
Every atom has no overall charge (neutral). This is because they contain equal numbers of positive protons and negative electrons. These opposite charges cancel each other out making the atom neutral.
